6 FAQs about [Lithium battery negative electrode materials cannot be used]
Can a negative electrode be used as a lithium-ion battery material?
To be used as a lithium-ion battery material, it is, however, not enough that the material has a high electronic conductivity and a high surface area. A good negative electrode material also needs to undergo a reduction during the lithiation step and an oxidation during the subsequent delithiation step.
What happens when a negative electrode is lithiated?
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
What are the limitations of a negative electrode?
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
What factors affect the apparent performance of lithium metal negative electrodes?
The factors affecting the apparent performance of lithium metal negative electrodes are as follows: various characteristics of the freshly deposited layer of lithium metal (morphology, nucleus shape, specific surface area), electrolyte composition, and the results of the interaction between the two (i. e., the formation of SEI).
Can lithium cobaltate be replaced with a positive electrode?
Two lines of research can be distinguished: (i) improvement of LiCoO 2 and carbon-based materials, and (ii) replacement of the electrode materials by others with different composition and structure. Concerning the positive electrode, the replacement of lithium cobaltate has been shown to be a difficult task.
Why were rechargeable lithium-anode batteries rejected?
However, the use of lithium metal as anode material in rechargeable batteries was finally rejected due to safety reasons. What caused the fall in the application of rechargeable lithium-anode batteries is also well known and analogous to the origin of the lack of zinc anode rechargeable batteries.
